Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 2,2,3,3-Tetrafluoropropyl benzenesulfonate.
2,2,3,3-Tetrafluoropropyl benzenesulfonate (CAS 65675-12-9), molecular formula C6H6O3SC3H4F4O and molecular weight 290.23 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of 2,2,3,3-Tetrafluoropropyl benzenesulfonate (C6H6O3SC3H4F4O) is characterized by a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, fluorine substitution. In reversed-phase chromatography, its retention is governed primarily by the polarity and ionization state of its functional groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
As a certified reference material (CRM), 2,2,3,3-Tetrafluoropropyl benzenesulfonate meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
